Description

  The present invention relates to a three-dimensional image generation apparatus, and more specifically, a plurality of cameras provided with a zoom lens are used to simultaneously photograph a subject from several directions, and the photographed digital image is used to obtain a three-dimensional image. The present invention relates to a three-dimensional image generation apparatus for generating an image.

  The use of electronic commerce, virtual museums, digital encyclopedias, and electronic catalogs using digital media such as the Internet and CD-ROM is increasing.

  In this way, when a user touches an object through a virtual space, not only a planar image such as a photograph but also a binocular stereoscopic view in which an actual object is in front of the eyes so as to bring a more visual effect. It is necessary to provide a three-dimensional image together in order to enable the user to freely select the three-dimensional effect by the user and the user to freely select the direction and posture of the object.

  As described above, in order to achieve various purposes such as the effect of education and provision of practical information on products, the use of 3D content is gradually increasing.

  However, conventionally, as a method for providing 3D content, an operator manually shoots an object to be photographed (for example, a sculpture, a product for sale, etc.) from several angles, and then combines the photographed photographs. There are a method of generating a single 3D image, a method of capturing a moving image and providing a moving image file.

  A method of creating a 3D image by combining a plurality of manually taken photos can provide an angle image according to demands of consumers (eg, buyers, viewers, etc.). There are problems in that the number of photographs taken to create 3D image content is large, and it takes a lot of time to shoot, and the 3D image generation process becomes complicated. There was also the problem of increasing production costs.

  Also, if the center point of the photo is shifted when shooting all the shooting objects multiple times, the shooting operation must be performed again from the beginning, and in the process of re-taking various angles manually There is also a problem that an operation error occurs due to the human vision and the angle of the camera lens.

  On the other hand, the method of capturing a moving image and providing a moving image file can be provided as a single electronic file after continuously capturing the object to be photographed using excellent photographing machine materials. However, although there is an advantage that the generation time of the electronic file is shortened and the generation process of the electronic file is easy, there is a problem that the image of the angle desired by the consumer cannot be obtained freely. In addition, since the size of an existing moving image file is too large, a Web server that provides the file cannot operate normally, and there is a limit to publicizing a large number of products or materials.

  That is, the conventional 3D content providing methods have many problems such as 3D content generation cost, work time, work cost, and customer dissatisfaction.

  The present invention has been made in view of the above-described problems, and its purpose is to reduce the shooting time by simultaneously shooting a subject from several directions using a plurality of cameras provided with a zoom lens. Accordingly, it is an object of the present invention to provide a three-dimensional image generation apparatus that can reduce the work time and thereby reduce the work cost.

  Another object of the present invention is to provide a three-dimensional image generation apparatus that can eliminate restrictions on the size of a subject by raising or lowering the position of a camera in the vertical direction.

  Another object of the present invention is to provide a three-dimensional image generation apparatus that is provided with a zoom lens in a camera and can shoot with a subject size enlarged or reduced to a desired size.

  It is still another object of the present invention to control the camera position using a system such as a computer or a remote controller so that the operator can adjust as desired at a remote location or at a desired position. It is to provide an original image generation apparatus.

  In order to achieve the above object, a three-dimensional image generation apparatus according to the present invention includes a turntable in which a subject is located and rotates a predetermined number of times by rotational force, and rotation control input from the outside. A turntable driving device for rotating the turntable according to a signal; a plurality of cameras for photographing the subject and outputting a digital image according to a photographing control signal input from outside; and the plurality of cameras Are fixedly installed at equal intervals, a support base that is connected to the base and is driven up or down by a driving force supplied from the outside, and an up or down signal input from the outside. In response, the support base height adjusting device for raising or lowering the support base, and an up or down signal to the support base height adjusting device. A subject photographing apparatus having an up / down switch that outputs a control signal, and a control system that outputs a photographing control signal to the subject photographing apparatus and generates a three-dimensional image using a digital image input from the subject photographing apparatus; And a communication interface unit for connecting the plurality of cameras and the control system.

  According to the present invention, since a plurality of cameras provided with a zoom lens are used to simultaneously photograph a subject from several directions, the photographing time is shortened, so that the working time is also reduced. Work costs can also be reduced.

  Further, by raising or lowering the position of the camera in the vertical direction, the restriction due to the size of the subject can be eliminated, and a three-dimensional image can be generated regardless of the size of the subject.

  In addition, the camera is provided with a zoom lens so that the subject can be photographed with the size of the subject enlarged or reduced to a desired size, and an operator can create a desired three-dimensional image.

  In addition, by controlling the position of the camera using a computer-like system or a remote controller, the operator can adjust as desired at a remote location or at a desired position, shortening the work flow distance of the operator. By doing so, the production efficiency of the three-dimensional image can be improved.

  The communication interface unit 600 is a communication module that supports IEEE1394 communication.

  Hereinafter, the operation of the three-dimensional image generation apparatus configured as described above will be described.

  First, the operator places the subject 100 at a predetermined position on the turntable 200, and first confirms from the LCD window 416 provided in each camera whether the subject 100 has been placed at an accurate position.

  Alternatively, after previewing an image of a subject photographed by each camera 410 on the screen using the “preview” item of the control system 600, if the subject position is accurate, the operator photographs using the control system 600. When a signal is input, each camera 410 captures the subject and outputs a digital image to the control system 600.

  On the other hand, the operator must change the position of the camera 410 vertically in accordance with the size of the subject. To explain this, the operator can use an up / down switch 450 provided on one side of the subject photographing apparatus 400. , The support table 430 is vertically lowered or raised using the support table height adjusting device 440, and the stationary table 420 attached with the camera 410 is vertically lowered or raised in conjunction with the support table 430. . That is, when the size of the subject is large, the operator presses the up switch among the up / down switches 450, the support base is raised by the support base height adjusting device 440, and the camera 410 is moved away from the subject 100. When the size is small, the down switch is pressed, and the support base is lowered by the support base height adjusting device 440 so that the camera 410 approaches the subject 100. For example, as shown in FIG. 4, when the operator presses the up switch among the up / down switches 450, the motor drive unit 444 causes the motor 443 to drive current so that the motor 443 rotates in the forward direction as many times as the number of the press. Supply. Then, the support base 430 whose shaft is connected to the motor 443 is raised along the LM guide 441 by the LM bearing 442.

  At this time, the position check sensor 445 checks whether or not the LM bearing has reached the rising limit point. If the LM bearing has reached the rising limit point, the position check sensor 445 determines the driving current supplied from the motor driving unit 444 to the motor 443. Cut off.

  In addition, the operator uses a zoom lens 415 provided in the camera 410 to shoot a digital image by shooting the subject 100 with the size of the subject 100 enlarged or reduced to a desired size with the position of the camera 410 fixed. Will be generated.

  The operator thus sets the shooting conditions of the camera 410 to the optimum conditions for shooting the subject, and then inputs a shooting signal of the subject using the control system 600.

  Then, the photographing signal of the subject of the control system 600 is simultaneously output from the communication interface unit 600 to the plurality of cameras 411 to 414. The plurality of cameras 411 to 414 simultaneously photograph the subject 100 in accordance with the photographing signal of the subject, and transmit a digital image from the communication interface unit 600 to the control system 500. At this time, the horizontal camera 411 captures the subject 100 from 0 °, that is, from the horizontal direction, generates and outputs a digital image of the subject 100 viewed from the horizontal direction, and the first tilt camera 412 outputs the subject 100. The image is taken at a 30 ° tilt angle, and a digital image of the subject 100 viewed from the 30 ° side is generated and output. The second tilt camera 413 is shot at the 60 ° tilt angle, and viewed from the 60 ° side. The vertical camera 414 generates and outputs a digital image of the subject 100 taken from 90 °, that is, from the vertical direction and viewed from the vertical direction.

  Then, the control unit 510 of the control system 500 stores the digital image input from the communication interface unit 600 in the storage unit 520 and outputs it to the display unit 530 to be shown to the operator. In addition, the worker converts the digital image stored in the storage unit 520 into a three-dimensional image using a three-dimensional image generation program, and creates a desired content.
